Way to choose standard tiles when purchasing<\/strong><\/p>\r\n\r\n\r\n\r\n<p><strong>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong>You should be familiar with the firm's tile symbols. You can also test tiles directly in the following ways:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Knock on the tile, if the tile makes a resounded sound, it means that the tile is hard and solid. However, this method does not apply to wall tiles.\r\n<ul class=\"wp-block-list\">\r\n<li>Put a few drops of water on the unglazed tile surface. Keep an eye on the water absorption process; the slower the tile absorbs water, the better. This procedure, however, should not be used with wall tiles.<\/li>\r\n\r\n\r\n\r\n<li>To check for tile warping, place two tiles face to face and see whether there is a gap. If there is, the tile is warped. The sort of tile with the smallest opening should be chosen.<\/li>\r\n\r\n\r\n\r\n<li>Examine the tile's surface. Make sure there are no microscopic air bubbles in the grade-1 tile. This will prevent further yellowing, fading, and scratching.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Ng\u01b0\u1eddi mua h\u00e0ng n\u00ean l\u1ef1a ch\u1ecdn nh\u1eefng th\u01b0\u01a1ng hi\u1ec7u uy t\u00edn \u0111\u1ec3 mua s\u1ea3n ph\u1ea9m.
